I'm looking for a program to generate permutations for 13 (or more objects), I found your site. Unfortunately, your site is restricted to 7 objects and the permutations generated cannot be copied (downloaded).. Can you help? I wish to use such a list to generate calculated expressions (I make global substitutions for the permuted objects (say, letters) of numbers and mathematical operators and then modify the expressions so as to be interpreted in a spreadsheet as mathematical expressions; e.g. "acbde" --> "2^3+1" --> "=2^3+1" --> 9).
But do you realize how many there are permutations of 13 obejcts? 6227020800. Is it what do you want to mess with? How many pages do you think this will take? How long will a file be that stores all the permutations?
6,227,020,800 will take approximately 6 GB of your hard drive.
